Guillermo del Toro and James Cameron have spent decades obsessed with adapting a 'cursed' work: 'At the Mountains of Madness'

Guillermo del Toro spent years developing a film adaptation of H.P. Lovecraft’s "At the Mountains of Madness."

James Cameron joined as producer in 2010, but Universal canceled the project in 2011 over its high cost.

Despite later attempts with other studios and backers, the movie never moved forward.

The story highlights how Lovecraft’s key horror novel has long attracted major filmmakers without reaching the screen.
